Biography
al-Mu'tazz was the son of al-Mutawakkil. al-Mu'tazz became caliph in 866, at only 19 years of age, in a situation where the Abbasid Caliphate was rife with power struggles between different factions. After a very bloody period of dealing with his various enemies he looked like he was coming out on top, but by then his coffers were empty and a rebellion among the soldiers turned his fortunes around. In the end he was taken prisoner, beaten and locked in a room to starve to death. He was 24 years old when he died.
